Abstract

A method of error correction during a soft handover process is disclosed wherein a radio network control node receives a plurality of versions of the same data block. Two or more of the received versions of the data block are combined to determine a substantially error corrected version of the data block. The resulting substantially error corrected version of the data block may then be forwarded to to other network nodes.
